3 Claims.

This invention relates to new and useful improvements in automobileheadlight structures, and it is among the objects thereof to provide anovel means of mounting the light bulb in a combined sealed type lensand reflector, in a manner to permit its removal without destroying theseal between the lens and reflector.

Further objects of the invention will become more evident from adescription of the accompanying drawing constituting a part hereof inwhich like reference characters designate like parts and in which:

Fig. 1 is a side elevational view of an automobile headlight unitembodying the principles of this invention;

Fig. 2' a view partially in cross section and partially in sideelevation of a portion of the reflector and the light bulb attachingmeans;

Fig. 3 a front elevational view of the interior of the headlightreflector and bulb with the named parts in register, as they areassembled; and

Fig. 4 a view similar to Fig. 3 with the lens and bulb holder in acompletely assembled position.

With reference to the several figures of the drawing, the numeral ldesignates a headlight reflector of mirrored glass, although theinvention is adapted for use with the metal reflectors. The numeral 2designates the glass lens which is joined to the reflector I by asealing annulus 3 which is spun r stamped on the flanged engaging facesof the reflector and lens in a manner which forms no part of the presentinvention.

As shown in Fig. 2, the reflector portion I is provided with a centralopening 4 of a diameter sufficient to allow the insertion of a lightbulb 5 which is mounted on a bracket 6 in a manner to be electricallyconnected with terminals I and 8. The bracket 6 is provided with wings 9extending from a flange l0 and on its inner face is provided with radiallugs H, there being three such shown in Figs. 3 and 4. The reflectorportion is provided with slots 12, somewhat larger than the lugs H,which are inserted through the slots in the manner shown in Fig. 3.

The sealing gasket I3 is disposed against flange ID of the bulb bracketand the inner face I4 of the reflector is cam-shaped so that whenbracket 6 is disposed in the central opening 4 of the reflector withlugs II in register with slots 12 on the inside of the reflector, thewings 9 will be rotatable to displace the lugs against the cam face I4in a way to draw the bulb bracket in sealing engagement with the flatsurface I5 of the reflector.

Because of the need for mounting the filaments of the bulbs in propervertical alignment, as shown in the drawing, one of the lugs ll is widerthan the others and registers with a correspondingly widened slot of thereflector so that the bulb bracket can be inserted only in a manner tobring the filaments in proper alignment in the reflector.

By constructing the reflector and bulb bracket in the manner disclosed,the light bulbs may be replaced without breaking the sealing jointbetween the reflector and lens, thereby eliminating the breakage of theglass parts incident to break ing of the seal, which is the principalfeature of the invention.

The construction of bulb bracket and the manner of its assembly with thereflector assures sealing of the lens and reflector at the joint of thereflector and bulb bracket, which is another important feature of theinvention as it affords a pressure seal by the act of assembling thebulb bracket on the reflector.

Although one embodiment of the invention has been herein illustrated anddescribed, it will be evident to those skilled in the art that variousmodifications may be made in the details of construction withoutdeparting from the principles herein set forth.

I claim:

1. In an automobile headlight structure, a

combined reflector and lens, the reflector having an opening withsealing faces adjacent the opposite ends of said opening and saidopening being of a size to permit insertion of a light bulb, a brackethaving a light bulb mounted therein and having a radial flange andradial lugs spaced to accommodate the thickness of the reflector walltherebetween, and a wing lug on the outer side of the bracket wherebywhen the bulb is inserted through the reflector opening the bracket maybe turned to draw the outer flange in sealing engagement with thereflector Wall.

2. In an automobile headlight structure, a combined reflector and lens,the reflector having an opening with seating faces adjacent the oppositeends of said opening and said opening being of a size to permitinsertion of a light bulb and having angularly spaced slots therein, abracket having a light bulb mounted therein and having a radial flangeand radial lugs spaced to accommodate the thickness of the reflectorwall therebetween, the spacing of the lugs corresponding to the spacingof the slots in the opening, and a swing lug on the outer side of thebracket whereby when the bulb is inserted through the reflector openingthe bracket may be turned to draw the outer flange in sealing engagementwith the reflector wall.

3. An automobile headlight structure as set forth in the next precedingclaim having a sealing gasket disposed between the outer flange andreflector wall.
